Flexible CIGS solar technology allows for lightweight, flexible solar modules that overcome limitations of traditional rigid glass modules. Ascent Solar produces flexible CIGS modules using a roll-to-roll manufacturing process and monolithic integration techniques. This allows their modules to be highly efficient, lightweight and flexible, making them well-suited for applications such as consumer products, transportation, defense, and building integration. Their technology and products target significant market opportunities in areas like portable electronics charging, electric vehicles, and building-integrated photovoltaics.
CIGS Solar Cells: How and Why is their Cost Falling?Jeffrey Funk
My master's students use concepts from my (Jeff Funk) forthcoming book (Technology Change and the Rise of New Industries) to analyze the economic feasibility of CIGS (Cadmium Indium Gallium Selenide) Solar Cells. Improvements in efficiencies and reductions in cost per area (through new processes and increasing the substrate size) are causing steady reductions in the cost of electricity from them. See my other slides for details on concepts, methodology, and other new industries..

This presentation summarizes history and recent development of perovskite solar cells. If you have any questions or comments, you can reach me at agassifeng@gmail.com
The most common type of solar cells are Photovoltaic Cells (PV cells)
Converts sunlight directly into electricity
Cells are made of a semiconductor material (eg. silicon)
Light strikes the PV cell, and a certain portion is absorbed
The light energy (in the form of photons) knocks electrons loose, allowing them to flow freely, forming a current
Metal contacts on the top and bottom of PV cell draws off the current to use externally as power
CIGS solar cells are one of the leading thin film solar cells to be made commercially viable. There are a lot of ways in manufacturing it and we have specialized a two stage process which gives advantages over material growth during commercial manufacture. An advancement of the two stage process is done to increase the throughput and maximize profits. A lab scale emulation of the commercial process is done to study device performance as a result of the advanced process. Factors such as reproducibility and elemental optimization were a concern and the reason behind these concerns were researched. This thesis serves as an experimental test bed to study device performance before up-scaling the growth recipe for pilot production.

2016 Clean Energy Trust Challenge - Silver High EnergyJames Woods
My company is leveraging market timing; where U.S. federal tax incentives for renewable energy are an all-time high, a Renewable Portfolio Standard exists for many states - Illinois must meet 25% compliance by 2025, Space Solar Power (SSP) is undergoing legislation with the Sunsat Act which would create a commercial power satellite industry, and low-cost entry into Space exists with nanosatellites.

Developing Resilience Through Diversity in the Welsh Photovoltaic IndustryGavin Harper
Far eastern manufacturers have significantly undercut European manufacturers in the production of crystalline silicon solar cells. Some have described this as a ‘Solar Trade War’. This presents a challenging context for the European Industry as crystalline silicon technologies comprise the bulk of the marketplace. In Wales, this situation has been given particular poignancy by the closure of Sharp’s module assembly in Llay, Wrexham – where imported silicon solar cells were assembled into larger modules.
For the UK, the regional context for this industry is emerging. Competition based on labour-cost is impossible so there is a need to discover distinct regional strengths in order to stay competitive. There is an importance to focusing on products which offer a high degree of Gross Value Added. This means focusing on strategic niches and technologies that whilst not perhaps offering the highest conversion efficiency, offer attractive returns through economic competitiveness.
There are a range of other PV technology trajectories – thin-film cells and excitonic cells which occupy a much smaller proportion of the marketplace, however, whilst presently less efficient, they promise the potential of continuous production processes that may enable them to be produced more cost effectively. Furthermore, the technical properties of thin film cells lend themselves to capturing diffuse light, whereas silicon solar cells perform better with direct light. This may be considered a good fit between the technology and the weather of the regional market the technology could potentially serve!
This paper provides an analysis of Wales regional strengths in PV, the interesting diversity of research into PV technologies within Wales with a view to how the nation can retain competitiveness in this arena. The work will build on extensive analysis and involvement already undertaken CSER for the DECC UK Solar Roadmap.
